Production of Metric Jammed Structures with Morpho
ORAL
Abstract
Sam Hocking, Chaitanya Joshi, Tim Atherton
Metric jamming is a process whereby particles embedded on a moving interface can become rigid and arrest further evolution of the interface. It can occur, for example, in emulsion droplets, bacterial colonies and the formation of bijels. The metric jammed state may be thought of as the ultimate limit of a sequence of arrest, unjamming, relaxing and subsequent arrest events, whereby the system ultimately becomes rigid both with respect to particle and shape degrees of freedom. In this talk, we explore such configurations with *morpho*, a program for shape optimization and where the surface is directly discretized as a simplicial complex. Mechanical and vibrational properties of these structures are also discussed.
